Despite the fact that the profession of machine operator belongs to the category of little-known occupations, its indispensability to society is not in doubt. Key responsibilities include create parts from various materials for the repair of machines and other mechanisms. Elaboration of details is available in the form of special drawings and the correctness verified by the creation of optical devices. Profession machine operator requires extensive knowledge in the field of the exact Sciences, drawing, physics. To conduct correct choice of material for such a worker must be a specialist in materials science, as well as to understand the electrical engineering and mechanics. Moreover, the self-correction and error control should be based on knowledge of usage of measuring instruments and the rules of setup of the machines, and then reviewing for accuracy. The final touch will be knowledge of the principles of calibration structures of components, their grinding and processing.
